INTERLOK GLOSS interior/exterior acrylic urethane DTM latex is the best choice when coating over old oil-based paints, where hand traffic and wear-and-tear are challenges, or anywhere that you need a super-tough, long lasting finish with high reflectance. Thanks to the special cross-linking formula, INTERLOK delivers corrosion resistance and adhesion that other paints can’t match. Available in several popular stock colors, or have your INTERLOK purchase tinted to your exact specifications by our in-store color experts.
